Danfoss sight glasses, SGP N, SGP SGP X

SGP is a line of sight glasses for high pressure applications

Sight glasses, SGP N, SGP I and SGP X, for high pressure applications, solder

SGP N and SGP I are equipped with sensitive indicators for light reflection, which varies depending on the moisture content of the refrigerant. SGP I is suitable for refrigerants with mineral oil, e.g. HCFC. Shows too high moisture content in the refrigeration system, lack of subcooling or lack of refrigerant. SGP I is available with a flare or solder connection. SGP N is suitable for non-flammable refrigerants such as HFCs. Shows too high moisture content in the refrigeration system, lack of subcooling or lack of refrigerant. SGP N are available with a flare or solder connection. SGP X, without a moisture indicator, shows a lack of subcooling, a lack of refrigerant, the liquid level in the system or the oil level in the compressor. It is mainly used to indicate the condition of the refrigerant as well as the level in the system or the oil level in the compressor.  SGP X is available with a flare or solder connection.  Ambient temperature: -50 ° C to +80 ° C. Max. Permissible operating pressure: PS / MWP = 52 bar.
